                        Overlay is a Module that is absolutely positioned above the page flow. It 
has convenience methods for positioning and sizing, as well as options for 
controlling zIndex and constraining the Overlay's position to the current 
visible viewport. Overlay also contains a dynamicly generated IFRAME which 
is placed beneath it for Internet Explorer 6 and 5.x so that it will be 
properly rendered above SELECT elements.

<p>The array is empty by default for Overlay,

Overlay which need to define their own set of CONTEXT_TRIGGERS
should concatenate their super class's prototype.CONTEXT_TRIGGERS

Sets the height on the provided header, body or footer element to 
fill out the height of the container. It determines the height of the 
containers content box, based on it's configured height value, and 
sets the height of the autofillheight element to fill out any 
space remaining after the other standard module element heights 
have been accounted for.
</p>
<p><strong>NOTE:</strong> This method is not designed to work if an explicit 
height has not been set on the container, since for an "auto" height container, 
the heights of the header/body/footer will drive the height of the container.</p>

The array of context arguments for context-sensitive positioning. 
</p>
<p>
The format of the array is: <code>[contextElementOrId, overlayCorner, contextCorner, arrayOfTriggerEvents (optional), xyOffset (optional)]</code>, the
the 5 array elements described in detail below:
</p>
<dl>
<dt>contextElementOrId &#60;String|HTMLElement&#62;</dt>
<dd>A reference to the context element to which the overlay should be aligned (or it's id).</dd>
<dt>overlayCorner &#60;String&#62;</dt>
<dd>The corner of the overlay which is to be used for alignment. This corner will be aligned to the 
corner of the context element defined by the "contextCorner" entry which follows. Supported string values are: 
"tr" (top right), "tl" (top left), "br" (bottom right), or "bl" (bottom left).</dd>
<dt>contextCorner &#60;String&#62;</dt>
<dd>The corner of the context element which is to be used for alignment. Supported string values are the same ones listed for the "overlayCorner" entry above.</dd>
<dt>arrayOfTriggerEvents (optional) &#60;Array[String|CustomEvent]&#62;</dt>
<dd>
<p>
By default, context alignment is a one time operation, aligning the Overlay to the context element when context configuration property is set, or when the <a href="#method_align">align</a> 
method is invoked. However, you can use the optional "arrayOfTriggerEvents" entry to define the list of events which should force the overlay to re-align itself with the context element. 
This is useful in situations where the layout of the document may change, resulting in the context element's position being modified.
</p>
<p>
The array can contain either event type strings for events the instance publishes (e.g. "beforeShow") or CustomEvent instances. Additionally the following
3 static container event types are also currently supported : <code>"windowResize", "windowScroll", "textResize"</code> (defined in <a href="#property__TRIGGER_MAP">_TRIGGER_MAP</a> private property).
</p>
</dd>
<dt>xyOffset &#60;Number[]&#62;</dt>
<dd>
A 2 element Array specifying the X and Y pixel amounts by which the Overlay should be offset from the aligned corner. e.g. [5,0] offsets the Overlay 5 pixels to the left, <em>after</em> aligning the given context corners.
NOTE: If using this property and no triggers need to be defined, the arrayOfTriggerEvents property should be set to null to maintain correct array positions for the arguments. 
</dd>
</dl>
<p>
For example, setting this property to <code>["img1", "tl", "bl"]</code> will 
align the Overlay's top left corner to the bottom left corner of the
context element with id "img1".
</p>
<p>
Setting this property to <code>["img1", "tl", "bl", null, [0,5]</code> will 
align the Overlay's top left corner to the bottom left corner of the
context element with id "img1", and then offset it by 5 pixels on the Y axis (providing a 5 pixel gap between the bottom of the context element and top of the overlay).
</p>
<p>
Adding the optional trigger values: <code>["img1", "tl", "bl", ["beforeShow", "windowResize"], [0,5]]</code>,
will re-align the overlay position, whenever the "beforeShow" or "windowResize" events are fired.

<dd>To enable fixed center positioning, as with the <code>true</code> option.
<p>However, unlike setting the property to <code>true</code>, 
when the property is set to <code>"contained"</code>, if the overlay is 
too big for the viewport, it will not get automatically centered when the 
user scrolls or resizes the window (until the window is large enough to contain the 
overlay). This is useful in cases where the Overlay has both header and footer 
UI controls which the user may need to access.
